Product Description

*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 3 Options Are Now Available ***

Option 1: 

Buy strengthened brass gears + hi-torque motors in quantity of 1 set for 1 mirror or 2  sets for both mirrors ($49.99 / $89.99). Requires 24 hour epoxy of brass gear onto main shaft in your unit.  You will re-use your existing main shaft and epoxy on a new brass gear section.


Option 2:

Buy strengthened brass gears pre-mounted to a new machined steel main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  Does not require any epoxy cure time to install, its plug and play.


Option 3:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can buy the gear/motor combo for one of both sides, and with the spur gear pre-attached to a new main shaft, or loose. Loose gear orders require installation of the spur gear onto the main shaft using 24 hour epoxy - please refer to the DIY article link above.  We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

  1. The only part you need to fix your non-folding mirror! 5 Star Review

    Posted by on 5th Aug 2020

    This motor drive unit was a perfect fit and easy to install on my 2007 Cadillac Escalade passenger mirror.

  2. Great product 5 Star Review

    Posted by on 28th Jul 2020

    Bought complete unit didn't feel like playing with parts , getting too old for that stuff. Replacement unit simple bolt on and go. Taking apart mirror for first time slowed things down but instructions very complete. Work great, faster deployment may consider doing other side just because.

  3. You May Want to Order the Assembly 5 Star Review

    Posted by on 25th Jul 2020

    The replacement parts are excellent quality--and what GM should have used to build the car, not a cheap plastic gear.

    I bought the pre-attached gears and motors for each side...and wish I had bought the complete assembled unit---it would have been much easier and less time consuming.

    This job is complex and took me a whole day--lots of mistakes, but I finally got it perfect on each side. .

  4. 2010 silverado 2500 5 Star Review

    Posted by on 22nd Jul 2020

    I bought the Gruven replacement motors and already assembled gears to repair my passenger side mirror motor. I bought the pair in case the other was to ever go bad.After repairing the passenger side, I was testing the new installation, and while testing, the drivers side stopped working. Jumped right on to it, and had both sides back in operations in a little less that an hour. The installation video was awesome and made the whole job a snap!

  5. Easy Installation 5 Star Review

    Posted by on 22nd Jul 2020

    A little tricky putting the spring back on. But if you mark everything as you take it apart, it will go back on easily.
    Works better than before.

  6. very well made 5 Star Review

    Posted by on 21st Jul 2020

    Cant say enough about how much better engineered this part is than the OEM part. Worked great and Gruven provided excellent customer service.

  7. 2008 GMC Sierra 2500 HD 5 Star Review

    Posted by on 16th Jul 2020

    Replace both motor units for the same price I would have replace 1 hole mirror (out of the dealership).
    Each motor took me about 45 minutes: totally worth it!
    Allow about a week after confirmation from gruvenparts for your order to come in
    Follow the instructional video, not complicated at all

  8. 2009 GMC faulty original mirror motors 5 Star Review

    Posted by on 13th Jul 2020

    Bought the Gruven replacement motors and worm gears to replace the faulty factory mirror motors. The parts came in within 3 days, very fast shipment.
    The PDF help file is very beneficial to show disassembly of mirror and installation of new motors with worm gears.
    The second mirror only took about 20 minutes start to finish, both are working perfectly thanks to these heavy duty parts.

  9. better than factory original 5 Star Review

    Posted by on 9th Jul 2020

    its not too difficult. Folds in and out smoother and faster and than good factory originals

  10. Mirror Finally Retracts 5 Star Review

    Posted by on 2nd Jul 2020

    I have owned my 2009 Suburban for 3 1/2 years. The mirrors retracted when I bought it but shortly afterwards the passenger side mirror worked intermittently. Upon digging into it, I found the gear had split but I couldn't figure out how to get to it so I put everything back together and left the motor unplugged. After 3 1/2 years and not wanting to buy a whole mirror assembly I did a search to see if anyone had a fix for it. That's when I found Gruven Parts and their motor and gear set. To save time I bought the gear already assembled. The installation video was awesome and made it easier to disassemble than when I did it the first time. Got everything installed and back on the vehicle and it works great.
